55
Some commands have ranges, while others are absolute. If a number
greater than the maximum range is received, it is automatically set to the
maximum number for that function. If a command is received that is not
understood, a "?" is returned. With absolute settings, "0" is off, 1-9999 is on.
The one exception is the Power command, where 0 is off and 1 is on.
To assure the projector can process a command, wait 3 seconds before
entering the next command.
Error Conditions
Not all commands are supported for all projectors. If an unsupported
command is issued, the command will be ignored. If a command is received
that is not understood, a ‘?’ character will be returned indicating the
command was not understood.
Limitations
The projector cannot respond to commands coming in at a high-rate.
Therefore, a delay must occur between commands to ensure that the
command gets properly executed. To assure the projector can process a
command, wait 3 seconds before entering the next command.
The Step column refers to increasing or decreasing the menu bar position
since the On-screen Display is not an exact match of values. For example,
Step 2 changes the data by 2 through the CLI (Command Line Interface).
The menu bar is up (or down) by 1.
